METALLIC CEILING OR SHEATHING.

To all whom it may concern:

Be it known that I, PETER EBNER, aI citizen of the United States,residing at Columbus, in the county of Franklin and State of Ohio, haveinvented certain new and useful Improvements in Metallic Ceilings orSheathings, of which the following is a specification.

My invention relates to metallic ceiling or sheathing, the object of theinvention being to provide improved locking means for locking thepanels, comprising the ceiling,

into engagement with each other and to so construct and arrange saidlocking means that the connection between the panels may be readily madeeither before or after the panels are united with the furring strips orsupporting framework.

A further object of the invention is to provide a frictional lockingmeans between the panels, the member of one panel being engaged with themember of the opposed panel by an upward movement in contradistinctionto the devices sometimes employed and in which the engagement of thepanels with each other is brought about by a lateral movement of one ofsaid panels.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

In the accompanying drawing: Figure l is an underside view of fourceiling panels constructed in accordance with the invention; Fig. 2 isan enlarged sectional view of the device; Fig. 3 is an underside view ofthe outer portion of one of the ceiling panels; Fig. 4E is a sectionalview illustrating the method of connecting adjacent edges of the panelsto furring strips hereinafter described.

Like numerals designate corresponding parts in all of the figures of thedrawings.

Referring to the drawing the numerals 5 designate sheet metalpanels ofthat character designed to be used in the construction of sheet metalceilings or side walls, these panels being cut or stamped to therequired size and suitably embossed or ornamented as desired. In theconstruction of each of the panels 5, one side thereof is bentrearwardly or upwardly to form an edge tongue or flangel 6 which in itsouter portion is curved inwardly and then outwardly as at 7 to renderthe tongue resilient by reason of such curvature. The opposite edge ofeach of the pan- Specfcation of Letters Patent.

els, with the exception of those panels which lie adjacent to the sidesof the room, is formed with an upwardly projecting portion which is bentdownwardly upon itself to form a loop 8. This loop likewise is to someextent resilient and is of such width at its lower or neck portion as topresent a comparatively narrow entrance. In the joining of two adjacentpanels the curved tongue 6 of one panel is forced through the narrowentrance of the loop of the adjacent panel thereby springing the outermember of the loop slightly outward and causing the outer edge portionof the tongue to engage the inner surface of the loop and to lie in theupper portion of the latter. rl`his engagement in conjunction with thepressure on the tongue of the outer member of the loop serves to form adesirable detachable locking connection of adjoining panels which can beproduced either before the panels are placed in position against theceiling framework or afterward.

It will be understood that the above described method of connecting thepanels may be carried out through one row of panels at a time and thatthe adjoining rows of panels when similarly united are connected withthe first mentioned row by causing their adjacent edges to overlap eachother in the manner indicated in Fig. 4, said overlapping portions beingsuitably nailed to the furring strips 3 which are secured at properintervals to the ceiling framework. It will be observed by referring toFig. 3 that the loop 8 is not of such length as to extend to the ends ofthe panel (which is also true of the tongue 6), thus providing a spacebetween the ends of the loops and tongues of two adjoining panels forthe free passage of the furring strips.

From the foregoing description it will be seen that simple and efficientmeans are herein provided for accomplishing the objects of theinvention, but while the elements shown and described are well adaptedto serve the purposes for which they are intended it is to be understoodthat the invention is not limited to the precise construction set forth,but includes within its purview such changes as may be made within thescope of the appended claims.

Having thus described my invention what I claim is:

1. In a metallic ceiling or sheathing construction, a sheet metal panelcomprising a substantially horizontal body portion heving one of itsedges formed With an upturned curved tongue portion and its opposingedge formed With e loop projection into which the tongue projection ofan adjoin-v ing panel is adapted to he inserted and held loy friction-alengagement of the parts7 the loop projection having zt reduced neckportion adapted to engage the curved tongue portion.

2. In a metallic ceiling or sheathing construction, a sheet metal panelcomprising a substantially horizontal body portion having one of itsedges formed with an upturned curved tongue portion and its opposingedge formed with a loop projection into which the' tongue projection ofan adjoining panel is adapted to be inserted and held by frictionalengagement of the parts, the loop projection having'st reduced neckportion adapted to engage the curved tongue portion, said tongue andloop portions being of lengths edges. y

ln testimony whereof I aiiix my signature in presence of two Witnesses.
